A method for transmitting in a passive activation system in a motor vehicle. Between each use-case module and a protocol driver an intermediate management layer is inserted that receives requests from the modules and stores them in a list according to oldness and priority ranking, selects a main request with the highest priority ranking, selects requests compatible with the main request, sends at least one grouped signal corresponding to the main and compatible requests to a portable activation device, receives back from the activation device at least one signal transmitted to the intermediate layer allowing the activation device to be located and then the location thereof to be sent to the case modules that sent the main request or a compatible request, and deletes the main and compatible requests from the list.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method as claimed in claim 1, wherein a compatibility of the requests is carried out with respect to a common location zone of said at least one portable activation means necessary for activating the functionality associated with a use-case module.
3. The method as claimed in claim 1, wherein the location requests from the respective use-case modules present in the list are compared one by one with the main request to find out whether these requests are compatible or not with the main request.
4. The method as claimed in claim 1, wherein, after the main request and the compatible requests have been deleted from the list, a previously incompatible request of the highest priority ranking and of the greatest oldness becomes the new main request and it is determined whether the other requests in the list are compatible or incompatible with the new main request.
5. The method as claimed in claim 1, wherein, when a subsequent request is sent to the intermediate management layer by a use-case module and stored in the list after at least one grouped signal corresponding to the main request and to the compatible requests has been sent to said at least one portable activation means via the protocol driver, and when this subsequent request is compatible with the main request, the location of said at least one portable activation means, which location is received back by the intermediate management layer via the protocol driver, is also sent to the use-case module that sent the subsequent request.
6. The method as claimed in claim 1, wherein time is counted in the intermediate layer after the signal has been sent from the protocol driver to said at least one portable activation means and, when this counted time is less than a threshold duration of validity of the location of said at least one portable activation means and a new request that is compatible with the main request that required the location of said at least one portable activation means is received in the list, the location is sent to the use-case module that sent the new request.
7. The method as claimed in claim 1, wherein, when said at least one portable activation means is not unitary, all the portable activation means are located.
9. The group as claimed in claim 8, wherein the transmission system comprises low-frequency means for sending to said at least one portable activation means and radio-frequency means for receiving from said at least one portable activation means.
10. The group as claimed in claim 8, wherein the send and receive means take the form of a plurality of antennas arranged at different places on the vehicle, a mathematical position of said at least one activation means being determined via at least one reception-end measurement of the power received back by each antenna from said at least one activation means.
11. The method as claimed in claim 2, wherein the location requests from the respective use-case modules present in the list are compared one by one with the main request to find out whether these requests are compatible or not with the main request.
12. The group as claimed in claim 9, wherein the send and receive means take the form of a plurality of antennas arranged at different places on the vehicle, a mathematical position of said at least one activation means being determined via at least one reception-end measurement of the power received back by each antenna from said at least one activation means.
